Before I begin like all posts & guides I do if you don’t follow instructions & wreck your android I will not be held responsible.
I am not forcing you to do this remember, I’m merely providing the guide & images, you need to provide the knowledge. With that said please don’t blame me if you mess up your device.
With all things to do with hacking & root you have to remember do this at your own risk.
THIS ONLY WORKS FOR THE VERSION OF CYANOGEN STATED & ONLY FOR THE G1 & WORKED ON SAPPHIRE 32B WHEN TESTED (No Hero).
You will have to do this every time you update your Cyanogen ROM.
To remove the hack just wipe everything using Amon_RA Recovery & reflash the ROM.
What This Hack Does/Info On The 10MB RAM Hack For 5.0.x & Above
The “10MB Hack” (as dubbed by all who use it) has been said to speed up your device & make it achieve processes a lot faster. This is done by taking a partition of your GPU (Graphics processing unit) & transferring it to your RAM, in saying that, this hack is not recommended for people who do a lot of 3D gaming on their phones as most 3D games tend to either crash or go slow after the hack is applied (due to the partition subsidized for the extra RAM).
Please Note (READ THIS IF YOUR WONDERING WHEN A 10MB RAM HACK IS COMING TO THE CYANOGENMOD 5.0.x SERIES!!): It was recently announced by PerShoot & Cyanogen that the 10MB Hack will no longer work on the 5.0.x & above series of CyanogenMOD Builds due to hw3d needing the memory on the new Éclair version of Cyanogen’s ROM so only the builds from 4.2.15.1 will be able to use the 10MB RAM Hack.

All thanks go to Daproy over at XDA for hacking this from Cyanogen’s kernel, PerShoot for providing some of the hacks at XDA, EmoGamer for the video guide, Troy for making the guide even simpler & good-looking & the guys & girls following Androlute on twitter, we’re nothing without our site supporters leading us to great stuff like this.
I had a look at this and decided not to do it. It’s really only relevant if your system is out of working RAM.
Android, by default, handles that situation by killing an app after telling it to make a tiny snap-shot of its state. An alternative is compcache 9again trade-offs) or defining a Linux swap partition on your sdcard (again trade-offs as swapping may require more I/O than just reloading the app with its ‘state’ refreshed.
I don’t usually run out of system memory space, so freeing up more won’t do me any good.
Assuming the code is the same, the biggest speed boosts come clocking to processor to the full 528MHz (CM & Dwang and others do this – at the expense of battery life) and using a fast sdcard (Class6).
I agree with what Steve says, but its always nice to have more RAM to work with. Having an extra 10MB translates to a couple more of my favorite apps in the background which means I can access them a WHOLE lot quicker than having to reopen them =)
yeah, exactly why i did this, i have lost so much hang time from switching back from apps and homescreens a lot. its a lot smoother. im glad i decided to go with this.
Same here Chris, the 10mb really comes in handy with heavily used apps on my G1 like Chomp and I’m clients!
Sweet I can feel the different feel, it even loads faster. Thew laoding app delay is cut in half. My Mytouch is zoom, zoom, zoom….
I like this content so much.Imagination is more important than knowledge.
@Koluis: Thanks for the nice words – http://www.absolutelyandroid.com/10mb-ram-hack-for-cyanogenmod-version-4-2-15/ check out that its the new design on the new site, I rarely check this site now as we have moved higher.
